摘要:: 为了合理确定大型LNG船在强顺风中的停车淌航时机，依据在航船舶在顺风中的淌航运动数学模型，推导出不同风速条件下大型LNG船从某一初始淌航速度降至某特定速度的淌航距离表达式。天津港的引航实践表明，所提出的大型LNG船停车淌航时机的估算方法是实用且可靠的，可为操船者确定船舶在强顺风中的淌航时机提供理论依据。

Abstract:: To determine the appropriate time for a large LNG carrier to drift in strong tailwinds,the mathematical model of the vessel’s drift motion in tailwinds can be used to derive the expression for the drift distance of a large LNG carrier from a certain initial drift speed to a specific speed under different wind speeds.The pilotage practice of Tianjin Port shows that the method proposed in this paper for estimating the timing for stopping engine of large LNG carriers is practical and reliable.It can provide a theoretical basis for operators to determine the timing for stopping engine in strong tailwinds.
